Abstract: A Computer Vision enabled Smart Tray (CVST) is designed for use in medical training, such as for Central Venous Catheterization (CVC). The tray is configured to hold a plurality of medical instruments. A support surface supports the tray with areas that are selectively illuminable, and a sensing system is operable to sense the presence of instruments or supplies in at least some areas of the tray. Background color is used by the computer vision algorithm to distinguish between tools and the tray. In addition, the computer vision algorithm is evaluated for accuracy in tool detection.

Abstract: A medical training system is provided having a housing, a phantom tissue simulant surface, an insertion hole, at least one medical instrument with a tip configured to pierce the phantom tissue simulant surface, a passage, at least one sensor, and a microprocessor. The system simulate a medical training procedure and the microprocessor is configured to read and process information from each of the at least one sensor in order to provide feedback to a user.

Abstract: A haptic robotic training system includes a haptic robot arm, a position tracking system, a scanning surface, a monitor and a computer. The robotic arm includes a haptic feedback system and holds a custom syringe in place. The position tracking system includes a positon tracking probe shaped like an ultrasound probe and a motion tracker. The scanning surface is a soft pad made from a synthetic phantom tissue. A simulation software receives the positioning data for the syringe from the robotic arm, and for the virtual ultrasound probe from the position tracking system and generates a virtual environment which mimics an actual ultrasound image. The user receives a real time feedback in the form of a haptic feel through the robotic arm, a virtual ultrasound image on the screen, and a performance feedback on the simulation software.

Abstract: A haptic needle insertion simulator includes a syringe compartment having a cavity and a retractable needle at an end of the syringe compartment. The needle is operable to retract into the syringe compartment when pushed against a surface. The cavity is configured to provide a force profile felt by a user holding the simulator and simulating a realistic feeling of insertion force.

Abstract: A haptic robotic training system (200) includes a haptic robot arm (300), a position tracking system (210 and 212), a scanning surface (208), a monitor (214) and a computer. The robotic arm (300) includes a haptic feedback system and holds a custom syringe (500) in place. The position tracking system includes a position tracking probe (210) shaped like an ultrasound probe and a motion tracker (212). The scanning surface (208) is a soft pad made from a synthetic phantom tissue. A simulation software receives the positioning data for the syringe from the robotic arm, and for the virtual ultrasound probe from the position tracking system and generates a virtual environment which mimics an actual ultrasound image.

Abstract: A regenerative brake of the present invention presents a hydraulic device disposed in a front hub of a bicycle wheel. The device allows the bicycle to recapture part of the kinetic energy that would otherwise be lost when braking and make use of that power either by storing it for future use or feeding it back into a power system to be used. The hydraulic device may also be stored in a rear hub of the bicycle wheel.
